Driving home from work. One mile from home got the big green wrench. Truck was running fine. Drove it home. Code reader says 1335 and defines it as: “crankshaft position sensor”

Googling 1335 indicates that it is something different. Any ideas

 

I would believe Google this time. "EGR Position Sensor Min/Max Stop Performance."

You may need to replace the EGR valve, however you can try removing the plastic cover and working the valve with a pair of vise grips and see if you can free it up. It has worked in the past for me.
